APPARATUS FOR MAKING COMPOSITION FLYING TARGETS AND BALLS.

SPECIFICATION forming part of Letters Patent No. 304,226, dated August26, 1884.

Application filed December 4, 1883. Renewed July 9, 1884. (No model.)

To all whom it may concern.-

Be it known that I, FRANK J. MoYnR, of Lockport, in the county ofNiagara and State of New York, have invented a new and Im- 5 provedApparatus for Making Composition Flying Targets and Balls, of which thefollowing is a full, clear, and exact description.

The object of my invention is to provide a new and improved apparatusfor casting and hardening composition balls,by means ofwhich apparatusthe balls can be formed very rapidly and without requiring much labor orhandling.

The invention, which is an improvement on Patent No. 219,557, issued toO. F. \Voodward, for a process of making target-balls, September 9,1879, consists in a mold for casting balls, which mold is formed of twosections, each composed-of a series of semi-spherical cups united toform apertures between the several cups, each section being providedwith two diametrically opposite half trunnions, which, when the sectionsof the mold are placed together, form a trunnion, which is held in asuitable bearing in a car or carriage running 011 a track. Under thesaid track kettles are placed, which contain the molten fluid mass fromwhich the balls are to be formed, which molten mass is automaticallyfilled into a 0 bucket lowered into the mass, and from the bucket isdelivered upon the molds. After the balls have been cast in a mold, andbefore the entire contents have cooled, the mold is inverted, and afterthe mold is inverted water 5 is sprinkled on the same, for the purposeof cooling the balls, suitable water-sup 'ily devices being held abovethe track. 7

The invention also consists in various parts and details andcombinations of the same, as 0 will be described and set forthhereinafter.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

4 5 Figure 1 is a plan view of a track-frame supporting the carriagesand molds for making composition target-balls. Fig. 2 is a plan view ofthe upper section of the mold for easting the balls. Fig. 3 is a planview of the '50 bottom section of the mold. Fig. 4: is an enlargeddetail cross-sectional elevation of part of a mold. Fig. 5 is an endelevation of the mold. Fig. 6 is a side view of the sprinkler, thefunnel for catching the water, and a bucket for casting composition intothe mold.

The mold for casting the balls consists of'an upper section, A, and abottom section, B, each of the two sections being composed of a seriesof semi-spherical cups or molds, A and B, respective] y, which areunited to form a cluster, as shown in Fig.3, small triangular or roundapertures or spaces a being formed between the several cups, throughwhich spaces air or water can circulate. The cups A of the upper sectionare inverted, and are each provid- 6 5 ed on the top with a neck, A".The upper parts of the cups A of the upper section are united by a plateor apron, A in which apertures are formed, which lead to the necks A thesaid plate A being provided with an upwardly-projecting flange, A. Eachmoldsection A and B is provided with a semi-cylindrical trunnion part,0, which trunnionsections are so arranged that the flat sides fitagainst each other, thereby forming a coniplete trunnion, on which themold can swing. By means of the said trunnions the mold is hung on theend bar, D, of acar or carriage, E, provided with wheels F, resting oncircular tracks G, the said bars of the carriage and the tracks G beingsuch a distance apart that the mold can be revolved on its trunnions.Under the tracks G one or more kettles, H, are placed, in which thecomposition for making the balls is melted. Above the tracks awater-conduit, J, is held, the lower end of which is closed by aperforated plate, L, which is held a short distance above the track.Below the said sprinklingplate L a funnel-shaped receptacle, K, is heldbelow the tracks, which receptacle is provided with means for carryingoff the water. By means ofsuitable tackle, M, a bucket, O, is suspendedfrom a beam over the track, which bucket is provided with an aperturedbottom closed by a valve-plate, 9 b A P, resting 011 the bottom, andprovided with stems Q, which project through and from the bottom of thebucket, and also project upward from the platel to the upper end of oneof which stems Q a cord, wire, or other means can be secured for raisingthe valve.

The operation is as follows: One of the ket tles H is always under thebucket O, and when the said bucket is lowered into the molten, fluidmass in the kettle the pressure of the liquid or fluid mass raises theplate I, thus permitting the fluid mass to enter. If the bucket israised, the pressure of the fluid mass in the bucket presses down thevalve-plate P, thereby closing the apertures in the bottomautomatically. The bucket is now raised out of the kettle, and highenough above the track to allow the carriage E, carrying the mold, topass under the bucket, and the bucket is then lowered down to the mold,the stems of the valve striking the apron and automatically opening thevalve-plate P, thus permitting the fluid contents of the bucket to flowupon the plate or apron A, and from the same, ,through the necks A",into the mold. The

mold is then permitted to stand for a short time until a coating orhardened mass has been formed on the inner surfaces of the mold. Thenthe mold is inverted, to permit the remaining fluid mass contained inthe mold to flow off through the necks A, the hardened mass on the apronA having been scraped oil previously. The mold is then run under thesprinkler J L, and water sprinkled on the surface of the mold, the waterpassing through the apertures a and over the molds, which, beinginverted, thus prevents the water from passing into thenecks A. The moldis then run to some convenient place, turned right side up, and openedand the balls taken out. It is then used again in the manner described.

In place of using two tracks, G, a single track can be used, thecarriage,.&c., being suspended from the same in some suitable manner. Asthe trunnions 0, formed of two half-sections, are held in bearings inthe end bars of the carriage E, the sections will be held together bythe said trunnions, and no special locking device is required.

In place of sprinkling water on the molds, the molds can be immersed inwater, for the purpose of causing the cooling and hardening of thehollow balls in the molds.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is l 1. A mold for casting balls, made,substan- I tially as herein shown and described, of two sections, eachcomposed of a series of united semi-spherical cups, between which cupsapertures are formed, as set forth.

2. A mold for casting balls, made substantially as herein shown anddescribed, and consisting of two sections, each formed of a series ofunited semi-spherical cups, and each section being provided with twoopposite halftrunnions, as set forth.

. 5. The combination of a mold formed of two sections, each composed ofa series of 7 united semi-spherical cups,with a carriage in which thesaid mold is pivoted, substantially as herein shown and described.
